re: WW-Inspired Question

Just looking at a movie involving boring trench warfare type of fighting with biochemical weapons mixed in, that if the participants or combatants I should say weren't wearing gas masks made for god awful ghastly death scenes just didn't make for thrilling action imo. Throw in the always bad gloomy weather conditions it seemed like and other crazy shite going on in those days, and that should give you an ideal as to why WWI wasn't much of an era in terms of making motion picture success happen.
